AI agents use gitrama_stream_switch to create or modify resources in Gitrama. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call gitrama_stream_switch repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Gitrama.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Args: name: Stream name (e.g., "auth-refactor", "payment-v2"). description: Optional description of the stream's purpose.. It is categorised as a Write tool in the Gitrama MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Gitrama MCP server in PolicyLayer and add a rule for gitrama_stream_switch: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gitrama. Nothing to install.
gitrama_stream_switch is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the gitrama_stream_switch rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gitrama_stream_switch. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gitrama_stream_switch is provided by the Gitrama MCP server (GitramaLLC/gitrama-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
